**The first MCP server to expose dynamic, AI-invocable tools for prompt generation and template assembly.**

Transform how AI assistants interact with specialized content. Instead of static prompts and resources, Mercury Spec Ops provides **6 programmable tools** that enable AI to dynamically generate technology-specific prompts and comprehensive templates on-demand. Built on a sophisticated modular architecture with **31 technology stacks**, **10 analysis dimensions**, and **34 template sections**—all accessible through simple tool calls.

## Features

This MCP server provides a modular, extensible architecture with:

### Prompts (Enhanced with Enum Support)

1. **PRD Prompt** - Generate Product Requirements Document with modular technology-specific analysis
2. **Codebase Analysis Prompt** - Analyze codebases with modular technology/focus-specific analysis
3. **Bug Analysis Prompt** - Analyze bugs with modular severity/technology-specific analysis

### Resources (Modular Templates)

1. **PRD Template** - Modular PRD template with technology-specific sections
2. **Codebase Analysis Template** - Modular codebase analysis template with technology/focus-specific sections
3. **Bug Analysis Template** - Modular bug analysis template with severity/technology-specific sections

## Key Capabilities

- **Comma-separated input**: "node.js,react,postgresql" or "security,performance,code-quality"
- Custom instruction integration
- Intelligent fallback to base prompts

### Modular Template System

- Template sections with dependency resolution
- Technology-specific template sections
- Focus-specific template sections
- Custom section support

## Installation

### Option 1: Local Development

1. Clone and install dependencies:

```bash
git clone https://github.com/n0zer0d4y/mercury-spec-ops.git
cd mercury-spec-ops
npm install
npm run build
```

2. Run the server locally:

```bash
npm run mcp
```

### Option 2: Install from npm

```bash
npm install -g @n0zer0d4y/mercury-spec-ops
```

Or use directly with `npx` (no installation required):

```bash
npx @n0zer0d4y/mercury-spec-ops
```

## Usage

### Integration with MCP Clients

Configure the server in your MCP client (Claude Desktop, Cursor, etc.):

#### Using npx (Recommended - No Installation)

**For Claude Desktop** (`claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "mercury-spec-ops": {
      "command": "npx",
      "args": ["-y", "@n0zer0d4y/mercury-spec-ops"]
    }
  }
}
```

**For Cursor** (`~/.cursor/mcp.json`):

```json
{
  "mcpServers": {
    "mercury-spec-ops": {
      "timeout": 60,
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@n0zer0d4y/mercury-spec-ops"]
    }
  }
}
```

#### Using Local Installation

**For Claude Desktop** (`claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "mercury-spec-ops": {
      "command": "node",
      "args": ["/path/to/mercury-spec-ops/dist/src/server.js"]
    }
  }
}
```

**For Cursor** (`~/.cursor/mcp.json`):

```json
{
  "mcpServers": {
    "mercury-spec-ops": {
      "timeout": 60,
      "type": "stdio",
      "command": "node",
      "args": ["/path/to/mercury-spec-ops/dist/src/server.js"]
    }
  }
}
```

**Windows Local Path Example** (Cursor):

```json
{
  "mcpServers": {
    "mercury-spec-ops": {
      "timeout": 60,
      "type": "stdio",
      "command": "node",
      "args": [
        "C:\\Development\\Projects\\MCP-Servers\\mercury-spec-ops\\dist\\src\\server.js"
      ]
    }
  }
}
```

**Important Notes:**

- **npx**: Automatically fetches the latest version from npm (recommended for most users)
- **Local**: Replace the path with your actual project location and run `npm run build` first
- **Restart**: Restart your MCP client after configuration changes

## Workflow Examples

### Example 1: Enhanced Codebase Analysis

1. **User Prompt**: "Analyze this Node.js/TypeScript codebase focusing on security and performance"
2. **Claude Desktop Action**:
   - Calls the `codebase-analysis-prompt` with technology_stack: "node.js,typescript" and analysis_focus: "security,performance"
   - System programmatically assembles: base prompt + Node.js module + TypeScript module + security module + performance module
   - The prompt instructs Claude to first read the `resource://codebase-analysis-template`
   - Template builder assembles: base template + Node.js sections + TypeScript sections + security sections + performance sections
   - Claude reads the dynamically assembled template
   - Claude analyzes the codebase and generates a comprehensive technology-specific report

### Example 2: Enhanced Bug Analysis

1. **User Prompt**: "Analyze this critical security bug in React application"
2. **Claude Desktop Action**:
   - Calls the `bug-analysis-prompt` with technology_stack: "react", severity_level: "critical", and bug_type: "security"
   - System assembles: base prompt + React module + security module + critical severity module
   - Template includes: general sections + React-specific + security-specific + critical-severity sections
   - Claude reads the bug analysis template
   - Claude analyzes the bug and generates a comprehensive technology and severity-specific report

### Example 3: PRD Generation with Technology Support

1. **User Prompt**: "Help me create a PRD for a React-based task management application"
2. **Claude Desktop Action**:
   - Calls the `prd-prompt` with project details and technology_stack: "react"
   - System assembles: base prompt + React module
   - Template builder includes: base PRD template + React-specific considerations
   - Claude reads the technology-enhanced PRD template
   - Claude generates a comprehensive PRD with React-specific sections
